To @ZZ wiz/0m, t ina/y concern,.-

Beit known that We, JOHN W. TAYLOR, of Reedsville, Miiilin county, and WILLIAM J. HUNTER, ofHuntingdon,Huntingdon county, Pennsylvania, citizens of the United States, have invented certain new and useful Improvements in Harvesting-Machines,ot' which the following is a specification.

Thislinvention relates to harvesting-machines; and the object thereof is to provide simple and eiective means for preventing the grain from choking at the juncture of the elevators and deck-board. A slight space necessarily occurs at this point to provide for free operation of the lower elevator, and as this space is directly beneath where the elevators discharge the tendency of the grain to catch therein and choke or clog is considerable, and especially so when it is short or tangled. lVe propose to obviate this diflculty by providing a bridge or guard for closing said space, having yielding engagement with the lower elevator. By this means the tendency to choke is obviated andany grain that may become lodged at said point is readily worked down by and discharged beneath the lower elevator.

In the accompanying drawings, Figure l is a detail perspective view of the elevators and a portion of the deck-board with our improvement in position. Fig. 2 is a vertical sectional view. Fig. 3 is a view similar to Fig. 2, showing a modification.

Referring to the drawings, 2 designates the deck-board, 3 and 4 the upper and lower elevators, and 5 the elevator-slats. 'Io assure the lower elevator free and uninterrupted operation, a slight space occurs between the same and the upper edge of the deck-board. To close this space, we provide a bridge or guard 6, which is preferably so curved or shaped that its lower portion 6' parallels the under surface of the lower, elevator 4 and is adapted to bear thereagainst. The bridge or guard maybe supported in anysuitable manner. In Figs. 1 and 2 the upper edge thereof is shown overlapping and secured to the upper face of the deck-board, while iu Fig. 3 it is shown hinged at 7 to the' edge of the deck-board. Springs 8 are shown secured to .the under side of the deck-board at 9, which bear against portion 6' of the guard and-hold the same against the canvas with a yielding pressure. If formed of spring metal and rigidly secured, as in Figs. l and 2, the guard may be sufficiently resilient to exert the requisite pressure without the springs, in which event the latter may be dispensed with. It will be understood, however, that the guard may be supported and caused to exert yielding pressure on the elevator in a variety of ways without departing from the spirit of our invention. Obviously it may be constructed of any suitable material.

With the bridge or guard arranged as shown its tendency is to deflectthe grain down over the deck-board as it discharges from the elevators.' If, however, any portion thereof lodges onthe guard, it is drawn downward thereover and discharged by the slats 5 of the lower elevator, which scrape downward over portion 6 ofthe guard as they descend. Thus simple and effective means is provided for facilitating passage of the grain from the elevators to the deck-board and for preventing choking at the juncture of said parts.

We claim as our invention- 1. In a harvesting-machine, the combina- -tion with the elevators and deck-board, of a bridge or guard closing the space intermediate said parts and having a yielding portion extending beneath the lower elevator, substantially as described.

2. In a harvesting-machine, the combination with the elevators and deck-board, of a bridge or guard closing the space intermediate said parts and having a free portion eX- tending beneath the lower elevator, and means for yieldingly holding said free portion of the bridge in close proximity to the lower elevator, substantially as described.

3. In a harvesting-machine, the combination with the elevators and deck-board, of a bridge or guard closing the space intermediate said parts and extending beneath and-adjacent the under side of the lower elevator, and means for causing the depending portion of the guard to bear againstsaid elevator, substantially as described.

4. In a harvesting-machine, the combination with the elevators and deck-board, of a bridge or guard closing the space intermediate said parts and secured tothe deck-board 6. Ina harvesting-machine, the combination with the elevators and deck-board, of a bridge or guard closing the space intermediate said parts and having yielding engagement with the lower elevator, substantially as described.

In testimony whereof We affix .our signazo tures in the presence of two Witnesses. JOHN WV. TAYLOR. WILLIAM J. HUNTER. Witnesses:
